ive got a 91 4x4 saff, t35 15psi, bayjoo stage 1 and the usual scorpion, pipercross, -31 etc. it, will sometimes misfire lightly under normal driving which you can rev through, but under load it will rev to between 4 and 4500rpm then lose all power, everytime you press the throttle it throws a massive flame out then cuts out, it will start up again straight away albeit turning over a fair bit more than usual. since the problem arose i have put on new plugs, motorsport leads, group a coil, rotor arm, dizzy cap, phase sensor, water temp sensor and rad sensor, checked the timing, checked the fuel pump is pulling enough voltage, but the problem is still here. i dont really want to spend any more money willy nilly on bits hoping it will cure it. HELP!!!! matt
